Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
You can use 'try: & except: return "Error" ' mechanics
Hi Kateryna, I too had problems with the error until I figured it out. Think about testing specifically for the missing property value inside the object, not a missing argument in the function. The description could do a better job explaining things. Hope this helps.
